To all whom, it may con/cera.- l ,I

Be it known that I, SAMUEL DIXON, a citizen of the United States, residing at Findlay, in the county of Hancockgjand-Stateof. Ohio, have invented certainjnew and useful Improvements in Kilns for Pottery, Suc.; and I exact description of the invention, ,such as will enable others skilled in theart to which it` appertains to make and use sthe saine, reference to letters or figures of reference marked therje-vA Figure 1 of the drawings is a representation;

Fig. 2 is a sectional plan of the floor. Fig. 3

- is avertical section taken through the lues H.

Fig. 4 is a sectional plan showing the construction of the circular lines. Fig. 5 is a front elevation of the kiln complete, and Fig. 6 is a sectionalplan showing the construction of the floor S.

This invention relates to improvements in brick and tile kilns; and it consists in the construction and novel combination of parts, as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, VGr represents the base of the kiln.

V is the support or shoulder for the door S, hereinafter described, to rest upon.

E E are the ireboxes,equally distant apart, and provided with proper grates, and have the ash-pits Z under them.

H H represent the chimneys on the inside of the kiln, having the sliding gates A nearl their lower ends, and the sliding gates B near their tops, and communicating with the reboxes E by the passages A', as shown.

I Iare four vertical chimneys on the outside of the kiln, and controlled `by the valves or sliding gates C. l

N N are the equidistant chimneys, which rise'from the kiln around the edge of dome, and are provided with the sliding gates O.

N is a chimney rising from the center of the dome, and provided with the sliding gate O', as shown.

R R are four radial cquidistant walls within the kiln upon its base. The purpose of the walls R is to divide the downdraft currents of l air andkeep the said drafts separate from each other. f K v F F are four horizontal lues runningl from the lower ends of the chimneys I to the center :of the base of the kiln, where the walls of the `fines unite. do declare the following to be a full, 'clear, v'and L L' are concentric circular dues at the base of the kiln, and M Mare straight iiues surrounded bythe formen., yThe lines L and M open into the large iiues F. being had to the accompanyingdrawings, and I X X are uprightbricks lin the walls of the f flues L M, and W W are openings'in said walls. on, which form a part ofthisjspecication.

V J is the door of the kiln, situated in any convenient position. of a vertical section taken through the ues I'.

I T are -chixnneys,j made of green or unburned tiles, which rest on the tloor S, as Shown,

- under the chimneyswN N f, and lare replaced every time the kiln is filled forburning. Each chimneyflv is between and equally distant from two chimneys, H.

when in place, rests with its rim upon the' circular shoulder V.

' Y is the foundation upon which the floor and the bricks or tiles that vmake the dues L and M rest.

I P are tiles, preferably about four by eight inches, and twenty-two inches long,which'rcst over the four Ilues F, the walls of theflues L M resting on the tiles, ,as shown. The door S is of general circular shape, and is composed at its central portion ofthe straight bars s', crossing each other at right angles and outside of the central portion of the radial bars s2 and curved bars sa. Its edge has the notches or recesses s4 for the accommodation of the lues H, as shown.

To cause an updraft through the kiln, close the sliding gates B and O and open the gates A, O, and O. rIhe draft will then be from the fire-boxes E into lthe Vflue H, and thence through the ues L and M and up the chim- IOO neys T N N. This causes both center and side npdraft. If a side draft only is wanted, the sliding gate O of the central chimney, N, is closed. If a center draft only is wanted, the gates O of the side chimneys, N, are closed.

To create a downdraft in the ki1n,.cl'ose the` gates A, O, and O', and open the gates B and C. The draft is now from the fire-boxes E into and up through the flues H, and thence down through the tile in kiln into the iues L and M, thence into the fines F, and up the chimneys I. In the first case the liring begins at the bottom, and in the second case it begins at the top. When the draftis too strong in any direction, the sliding gates can be partially closed, so as to regulate the same.

A kiln may be arranged to have a downdraft only: by omitting the chimneys N, N, and T and the sliding gates B in the chimneys H. The draft will then pass up said chimneys and descend thence, pass under the reticulated floor, and go up the chimneys I.

A kiln may be arranged for one updraft only by omitting the chimneys I and the sliding gates B in the chimneys H. The draft will then be down the chimneys H,under the Hoor, and up through the chimneys T N N. These, however, are but modifications of the kiln, having both up and down drafts, as described.

A kiln may be arranged with four, ve, six, seven, or more fire-boxes, E, and with as many chimneys, H, T, and N. A kiln fteen feet in diameter should have four fire-boxes. A kiln eighteen feet in diameter should have ve fire-boxes. A kiln twenty feet in diameter should have six re boxes. A kiln twenty-two feet in diameter should have seven municating with= said re-boxes and having the sliding gates A B, the outside chimneys, I, having the sliding gates C, the dues F, and flues L and M, communicating with the lilies F, substantially as specified.

2. In a kiln, the combination,with the oven or body, the reticulated floor S, the fire-boxes, and the flues L and M below the same, and

constructed substantially as described, of thechimneys I N N, respectively provided with the gates C O O', the lines H, provided with the gates A B, and the temporary lues T, made of unbaked or green tiles, substantially as specified.

3. In a kiln having iire-boxes E, the combination of the oven-body,the reticulated floor S, and the fines L and M below the same,with the chimneys I N N, respectively provided with the gates C O O, the nes H, provided with the gates A B, and the temporary flues T, made of unbaked tiles, substantially as specified.

In testimony whereof I affix my signature 1n presence of two witnesses.
